Triangulate Node

The Triangulate node converts all faces in a mesh (quads and n-gons) to triangular faces. It functions the same as the Triangulate tool in Edit Mode.

Inputs

Mesh

Standard geometry input.

Selection

A standard Boolean selection input to determine which faces will be triangulated.

Minimum Vertices

Minimum number of vertices a face must have to be triangulated. For example, setting this value to 5, will prevent triangulation of Quads and only triangulate N-gons.

Properties

Quad Method

Beauty:

Split the quads in nice triangles, slower method.

Fixed:

Split the quads on their 1st and 3rd vertices.

Fixed Alternate:

Split the quads on their 2nd and 4th vertices.

Shortest Diagonal:

Split the quads along their shortest diagonal.

Longest Diagonal:

Split the quads along their longest diagonal. This is the preferred mode for cloth simulations.

N-gon Method

Beauty:

Arrange the new triangles nicely, slower method.

Clip:

Split n-gons using an ear-clipping algorithm (the same method of tessellation used for viewport display).

Outputs

Mesh

Standard geometry output.

Example

Mesh before triangulation.

Mesh after triangulation.
